What is fibromyalgia?

Fibromyalgia is a chronic, long-term illness. It causes all-over muscle pain, joint pain and fatigue. The pain may come and go. There’s no known cause, although certain factors such as stress and genetics may predispose someone toward the disease. Although there isn’t a cure, medications, lifestyle changes and other therapies offer relief.

Who might get fibromyalgia?

Anyone can get fibromyalgia, including children. Women are twice as likely as men to have fibromyalgia. Symptoms often appear during middle age. Up to 20% of patients who suffer from other chronic disorders such as rheumatoid arthritis, lupus and sarcoidosis can also have fibromyalgia.

Basic blood tests are recommended to exclude other causes of fatigue such as anemia or thyroid disease. The diagnosis relies on your family and medical history combined with your symptoms.
